Severe weather to erupt across the South amid flooding threat this week

A slow-moving storm system tracking through the southern tier of the United States will bring the threat for heavy rain and severe thunderstorms to the South through midweek.
The first round of thunderstorms targeted portions of the lower Mississippi River Valley, Tennessee Valley and lower Ohio Valley on Monday night. A confirmed tornado touched down just to the northwest of downtown Nashville around 12:30 a.m. CDT Tuesday.
Along with the threat for thunderstorms, the concern for flooding will increase into midweek across the South as this storm system brings a multi-day rain event to the region.
As the storm system approaches Texas on Tuesday, the ingredients for severe weather are expected to come into better alignment across the Lone Star State toward nightfall.
Tuesday night, more storms capable of producing damaging wind gusts, hail, torrential downpours and even an isolated tornado or two may target places like San Antonio, Austin and College Station, Texas.
The threat will continue to march eastward on Wednesday as the storm system taps into an ample amount of moisture in the Gulf of Mexico.
Warm and humid enough air to support robust thunderstorm development is expected to be limited to along the Interstate-10 corridor along the central Gulf coast.
The exact location of the center of the storm system and how far north an advancing warm front can extend will help to determine where thunderstorms erupt.
Residents in cities along Interstate 10, including Houston, New Orleans, Mobile, Alabama, and Pensacola, Florida, will need to remain alert for rapidly deteriorating conditions.
If the warm front shifts farther north, then that would allow the severe threat to encompass the Interstate-20 corridor.
On Thursday, this line of thunderstorms will shift farther east and may clip parts of southern Georgia and northern Florida. Although severe is anticipated to be more isolated than on Tuesday night and Wednesday, thunderstorms can still produce torrential downpours and locally damaging winds.
Regardless of the severe thunderstorm potential through midweek, the largest weather threat will likely come in the form of flash flooding.
Showers and storms will likely train over the same location, bringing round-after-round of heavy rain, which may cause already swollen rivers to recede even more slowly and eventually rise.
Many locales across the South and Southeast will get a chance to dry out this weekend as an expansive area of high pressure ushers in dry and cooler conditions.
